This patch would try sort the command list in monitor at runtime. As a result,
command help and help info would show a more friendly sorted command list.
For eg:
(qemu)help
acl_add
acl_policy
acl_remove
acl_reset
acl_show
balloon
block_passwd
...
the command list is sorted.
v3: using qsort function to sort the command list.

Applied. Thanks.
